Balthazar (Alexandria Quartet; Book 2) by Lawrence Durrel

The four linked novels that comprise English author Lawrence Durrell's masterpiece, THE ALEXANDRIA QUARTET, are set in Alexandria, Egypt, around the time of WWII. The four novels explore the city's polyglot society, full of intrigue, mystery, and sensuality, telling essentially the same story from different points of view. In BALTHAZAR, Darley reconsiders and retells the story he told in Justine, using information from a mysterious new character, Balthazar.
